Inventor: KATAYAMA HIROYUKI
IPC: B01D53/77
Filed: 2001-03-12
Abstract: PROBLEM TO BE SOLVED: To easily prevent the generation of blue smoke by a sulfuric acid mist at a low cost. SOLUTION: A flue 1 for introducing the flue gas of a boiler, etc., to a chimney 9 is provided with a wet process electrostatic precipitator(EP) 7 for capturing the sulfuric acid mist in the flue gas and the flue on the upstream side of the wet process EP 7 is provided with a sodium carbonate supplying system 10 for injecting sodium hydrogencarbonate powder.
